...subject to arrest... Huh? How does that work?

It means that the officer can either arrest you or just give you a citation or just a warning but before he decides which one he wants to know your name.

Failure to give your name at that point will make his decision easier.

So we are all “subject to arrest” at all times.

You do see the problem with that, right?
